Turning off any network computer stops network communication for 4 to 7 seconds for everyone else

I am on a small network with 23 users using mixed operating systems. 8 of the computers use Windows XP and the other 15 are on Windows 7. There is only one domain controller which is Server 2008 R2. The domain controller is our file, certificate, DHCP, and AD server. Three weeks ago an issue started occurring where network activity would stop for brief periods of 4 to 7 seconds of time at random times over the course of each business day. Not a big delay but when people are accessing databases and the TCP randomly drops, then my life becomes a nightmare.Last night we left all of the computers on and working on various things to see if there was a load issue.  Everything ran like a dream for almost four hours until we decided we were done testing. We turned off one computer and network communications stalled. We turned it back on and got all of the computers running the database that stalled out back up. We determined that if any network computer was turned off on the network communication for all other computers would cease for 4-7 seconds.

What we have tried

We changed out the cables on the servers (they were old) to the switches
We replaced the switches (they were even older) with new Gigabit switches  
Wiresharked a few PCs and the server to try and see where the failures are happening.
Turning everything on and running as many items as possible to see if the load is killing us.

Sounds like a computer might be the Computer Master browser

Check to see who is the Master Browser

doraemonzAuthor Commented:
The domain controller is the Master Browser. The service has been shut off on all other running computers.

Okay. To add a bit ore strangeness. When PCs are turned on or added the same issue occurs and all network activity stops for 4-7 seconds.

Do you have malware/virus software running on computers

doraemonzAuthor Commented:
Yes. We use Malwarebytes and Vipre on the computers. The antivirus and antimalware has been running since before the behavior started.

I would look hard at the NIC in the server.

Is the server and the computers on the same switch?

Do ipconfig /all for a computer and the server and post

Yes the server and most of the computers are on the same switch but the network drops occur even on the other switches.

can i see ipconfig /all from computers xp and win 7

also what type of router do you have

When you say the network is out

do they loss access to the internet

do they loss access to server shares?

Can you logon to the server when this is happening

we should run

dcdiag >>dclogx.txt
dcdiag /test:registerindns /dnsdomain:networkname.local >>dclogx.txt
dcdiag /c /v >>dclogx.txt
dcdiag /test:dns >>dclogx.txt

We have a SonicWall TZ210 router
Whe I say the network is out the entire work loses TCP IP connectivity for 4-7 seconds. Server shares stay up.

The dcdiag looks good. no issues there

How man switches do you have?

How are they connected to the router?

Can you get me an ipconfig from a XP and win 7 computer?

doraemonzAuthor Commented:
There are three switches. Two Adtran Netvanta switches for the PCs and one POE switch just for the IP phones. I am not at the office but will post on Monday.

Thomas GrassiSystems AdministratorCommented:
I see you have a POE switch. How many POE devices are on this network?
Are the POE devices on the same subnet?
IP phones can saturate the network.
This could be your issue.

Do you have any computers plugged into the poe switch?

Plug each switch into one of the lan ports on your router.

Make the lan port for the poe switch a QOS port. see manual below

http://static.freedomvoice.com/weblink/agent/SonicWALL_Internet&QoS_Guide_V1.0.pdf

Try not to mix computers and phones on same switch would be even better if the poe devices where on a different subnet.

Since on the subject of discovery do you have any wireless routers? How many wireless devices.
0
doraemonzAuthor Commented:
The phones and computers are on separate switches. The POE switch is on the same subnet. There is no wireless.There are 24 phones on the network.
0
Thomas GrassiSystems AdministratorCommented:
How are the switches connected to the lan?

1. do they each plug into a port on the router?

2. or are they plugged into each other then one to the router?

If no 2 then plug each switch into a sepreate port on the router.
Put the POE switch into a QOS port on the router.

If no 1 then make sure the poe switch is on a QOS port on the router.

Seen issues with IP Phones on the same LAN we have 30 plus IP POE phones but we have them on a seperate LAN and a seperate router.

But you can have them on the same lan as long as you assign qos to the port and they are not daisy chained together.

Great

I would get either HP or cisco switches we use them every where and never have issues they just run.
